Digital subtraction angiography method in which uncontrasted two-dimensional image data are extracted from already recorded computer tomography three-dimensional data

摘要

Digital subtraction angiography method in which an image of a body area, especially containing blood vessels, is produced by subtraction of a first image from a second image of the same area. The first image is produced without contrast enhancing agents, while the second is. The image data of the first 2D data set are calculated from a 3D volume data set of the same area.
